Composer William Bolcom. He is best known for his humorous and accomplished piano accompaniment of his wife, the singer Joan Morris, in their performances of American popular songs. His own compositions include the vast choral cantata "Songs of Innocence and Experience," that sets the poems of William Blake to music. He won this year's Pulitzer Prize in Music. Bolcom is also renown for his ragtime compositions, especially his work "Graceful Ghost."
